The present invention relates to `machines and appliances for lling grooves or open joints in concrete roads or other surfacing structures, and aims to provide a novel and 5 improved machine for convenieintly lling i the grooves or joints. u

@ne object of the invention is to provide a machine by means oi which tar, asphalt or other similar material rendered plastic by 10 heat.; or other plastic material, may be conu veniently poured into the groove or jointn Another object is to provide such a inan chine by means of which sand or other granular material may be poured into or over 15 the groove or oint.

A further object is to provide a combina.e tion machine by means of which either or both of the plastic and granularmaterials may be discharged under control by the operator.

A still further object is to combine receptacles or containers for the plastic and ranular materials in combination with a rebox in order that both materials are heated, so as to render the tar, asphalt, orsimilar material plastic9 and to dry the sand or other granular material. i

The invention also has for an object to provide novel means for mounting the machinefor movement over the groove or joint, .and novel means for controlling the dis char e of the plastic and granular materials.

With the foregoing and other objects in View, which will be apparent as the description proceeds7 the invention resides in the construction and arrangement of parts, as hereinafter described and claimed9 it being understood that changes can be made Within ing from the spirit of the invention.

The invention is illustrated in the accoml p partying drawings, wherein- Figure l is a side elevation of the improved machine.

the scope of What is claimed, Without depart- A container or receptacle lt) is provided for holding the asphalt, tar or similar nia teriai, and said container has a removable cover or top 1i which may he removed for filling the ycontainer and stirring); the material therein. A discharge pipe l2 entends downwardly and rearwardly treni the battono. out the container l0 iter the tlovv of the plastic material trein said container, and terminates at its rear end in a downwardly extending spout 13 which is "preferably dattened side- Wise or reduced in width, as seen in Fig. 5.

The material discharged troni the spent i3 is permitted totlovv into a ,groove or open joint 14 formed in theconcrete road or other surfacing;` structure, in order to lill said groove or joint and thereby seal the joint and exclude rain and moisture therefrom.

The plastic material container l@ is mounted on a iirebon l5 by means of support ing brackets l@ secured to the lower portion of the container l@ and rest-ineA on the rim et the Firebox. The lovver portion oit the con-` tainer 10 is disposed Within the mouth out the firebox 15, and the brackets l@ are preferably secured to the 'vt/all oi' the reboa to render the structure rigid. riihe rebon is of larger diameter than 'the container l@ to permit the products ot combination to pass upwardly between the container and rim of the Firebox. The discharge pipe l2 entends rearwardly through the Wall of the arebox, with the spent i3 in rear otsaid iirebox, as seen'in Figs, l and 3. The wall of the i'irebox is provided Ywith a snitable door l? that may be opened ier placing Wood? coal7 charcoal or other fuel Within the '.rebox, 'to provide the heat ier melting 'the material in the corn tainer lil.

The lire box l5 is mounted en a carriage comprising a suitable metal 'trarne iii, with a iront rt/heel 'i9 tivo rear Wheels 2l mount ed on the respective arles 22 and Q3. Fthe iront Wheel l) is a pilot Wheel to guide the machine along the grooveor joint Til-t, inasmuch as said wheel has an annular pilot iiange 20 adapted to rnn in the groove er joint? with theivheel 'i9 bearing on the snrace ot the concrete at opposite sides et the groove.

Braces 2 are ivotally connected with Athe opposite sides o the tirebox 15 and are secured to the bars 24 by means of which bolts 27, the brace bars '26 having apertures 28to receive the bolts127 for ,adjusting the bars 24 to different inclined positions for "the convenience of the o erator. The container or Iec'eptacle 29 f or t e sand or other granular faterial is of annular form l to surround 'the'conta'ine'r 10, and has the outer and innercylindrical walls 30 and 31, respectively. The container 29 seats on" the u brackets 16, 4and the inner wall 31 is of larger diameter than the container thus providlng an annular space 32 between the two contalners whichfprovides a discharge ilueffor the imroducts -of combustion that rise .from l the box around the container 10.

40 and swinging the valve 38 open.

-The flow of plastic material from the spout 1 3 is controlled by a valve 42 slidable 'in the spout 13 lengthwise of the slot of the spout, in order to regulate the discharge of the plastic material. The valve 42 is pivoted to an arm 43' on a rock shaft 44 mounted for turning movement on the frame 18 of the carriage, and a longer arm 45 at the outer end of s aid sl1aft44.is connected bya link 46 with the lower end of a slide rod 4 7 movable in o'uides 48 secured on o ne bar 24', said rod 47ll1aving afinger ring or` handle 49 at its be Conveniently grasped by the operator for pulling throd l47 so as to move the valve 42 open. A coiled ,spring 50 on the rod 47 is confined between one guide 48 and a collar 51A secured on said rod, to move the valve 42 to closed position.

For conveniently propellin the machine,

a sprocketwheel 52'is secure `to one of the rear wheels 21 and is connected'by 'an endless `frebox 1,5, or for poking or stirring the mateials im the containers 10 and 29. ,The rod 58 is normally held by asle'eve 59 carried by -.the container 29 through which the rod is inserted downwardly, in order that the rod is convenientlyl'carried by the machine.

The' operation of the machine is simple, it being apparent/that the machine is moved joint 1 4 which is facilitated by the moveinent of the flange 20 ofthe pilot wheel in said groove, and the valves '42" and 38 are' controlledby the operator for the roper ,or desired dischar e ofthe materials. vh e materials may' thus be discharged at a ratein proportion'to the speed of movement of the machine, and the discharge of mavin Fig. 3, the plastic material is discharged f from the spout the sand or granular material'is discharged 35 in rear' of the spout 13 so that the sand ors'imilar material is distribf plastic material. 4It'will be understood,how`ever', that the grooveor joint I may be'iilled with either `theplastic material or thegranular'material', or both? iThe valve grasped by the operator forpulling me chain 13 tofill the groove '14 andN 3 8 extendingrearwardly and downwardly' will discharge the l'granular',material rearvwardl'y from the spout 35 and'will spread such material transversely las to spread/ over the `plastic material delivered into the groove. i

This machine therefore enables the grooves or open joints in concrete roads and other sur- Jfacing structures to be conveniently lled in an eiicient manner and at minimum cost.

Having thus described the invention, what is claimed as new is l. A` machine of the character described comprising a carriage, a plurality of material containers mounted thereon and each having a discharge spout for delivering the material into aV groove or joint of a surfacing structure, and means for controlling the discharge of materials from said spouts, one container surrounding the other and having its spout located in rear of the spout of said other con'- tainer.
